Description

The invention relates to ventilation and can be used to remove contaminated air from a livestock building.

The aim of the invention is to increase the efficiency of the mine by increasing traction during exposure to direct sunlight.

Figure 1 shows an exhaust shaft, a transverse section; figure 2 - view And figure 1.

The exhaust shaft contains heat insulating walls 1, a panel 2 on the south side with an air gap 3 and an outer layer 4 that is transparent to solar radiation and an umbrella 5. The mine has a rectangular cross-section shape. The large walls 1 are oriented in the north-south direction. Panel 2 is made in the form of a window unit 6 with double glazing, and the inside surface 7 of the shaft is adapted to absorb solar radiation. A rotary valve 8 is installed inside the exhaust shaft to regulate the air output.

Exhaust mine works as follows.

In the cold period of the year, with the fixed position of the rotary valve 8, the air output of the shaft depends on the temperature difference equal to the difference between the air temperatures inside the room and the outside air.

As the outside air temperature rises, mine performance should decrease. However, in transitional and warm periods during daytime under sunshine, the productivity of the exhaust shaft increases dramatically, since the solar radiation coming in through

The window unit 6 on the inner surface 7 of the shaft causes heating, in the air in the mine, as a result of which the temperature difference increases.

The arrangement of the panel 2 in the form of a window unit 6 on the south side makes it possible to increase the temperature difference during the period when the outdoor air temperature increases. Orientation of the large sides of the mine in the north-south direction makes it possible to increase the area of the window block 6, i.e. accordingly, increase the surface heating area 7 inside the exhaust shaft.

Air is emitted into the atmosphere through an opening between the walls 1 and the umbrella 5.
